Don't believe whatever else you're seeing on the internet right now. This is not an April Fools prank gone wrong, nor is that a student on the ground here. It turns out the poor victim of nut-smashing is actually a fellow teacher who volunteered for the act. Even better, he took it like a champ and shrugged off the whole thing when it was all over:

This kid really earned the "ball boy" title this week at the Australian Open, even if his own set may not be functioning properly anymore.,br/>
Spain's Feliciano Lopez whacked him right in the nuts with a 121mph serve that had poor boy keeling over in pain.

He was escorted off the court but returned to his duties a few minutes later.
